That's easy. EBS and similar solutions comes with the price. They're very expensive. Especially, when you need a lot of IOPs. You may be saving on cross-AZ traffic but you will pay ridiculous amount of money on storage. If you have replication you can use attached storage which is way cheaper.
- rcarmo 3y agoAzure Managed Disks are inherently replicated. But there are other storage solutions (like redundant WebHDFS) you can take advantage of. At the time, the customers I was talking to wanted to have identical deployments in the cloud (to what they had on-premises, down to the number and size of disks).
